the PC data files could be recompressed back but you need a PKWare Data Compression Library software which costs 500 bucks!!!
The unpacker is a reverse engineered C code (dynamite). the compressor is not publicly available.
The idea (at least on PC) maybe would be to "repack" PC file in "store" mode (no compression).
I had tried the uncompressed files on my PC version and it failed.
Good work Kroah you rule!!! But I admit it's a difficult project. My remake is currently on hold too because of all the technical problems (isometric shit, lack of time ...)
